Cement, Lime, Plaster & Mortar

For the Transverse test of pozzolana and cement mortar prisms by single point loading of a 60 mm long prism supported at 100 mm centres. Smaller loads, less than 10 N, can be applied and measured with an accuracy of 1% in the upper four-fifths of the range. The load is increased at the rate of 40- 60 N/sec.

The failure loads of mortar cubes can vary considerably according to the type of cement and the period of curing. However, a capacity between 50 kN and 500 kN encompasses the majority of test conditions. A 500 KN Compression Testing Machine is suitable for testing mortar cubes, cement mortar and pozzolana cubes of 50 mm.

The jolting apparatus consists of a rectangular table, rigidly connected by two support arms to spindle at a horizontal distance of 800 mm from the center of the table. The table can be raised and allowed to fall freely by a cam, which is connected to a motor. The cam rotates at a rate of 60 rpm. A stroke counter, fitted with micro switch, is provided, which stops the machine after 60 jolts. Locating pins are provided for mounting the mould compartments on the table. The mould, surrounded by the hopper, can be clamped rigidly to the table.
Supplied complete with mould and hopper. And operation with 230 V, 50 cycles, single phase, AC Supply.

This apparatus has specially been designed to prepare cement mortar for strength determination as specified in IS: 4031. It can also be used in mixing lime with pozzolonic materials for determination of lime reactivity (as per IS: 1727) and for uniform mixing of soils with additives such as lime, cement, etc. The stainless steel mixing bowl has a capacity of 4.75 litres. The paddle, also made of stainless steel, can have both planetary and revolving motion for uniform mixing. It can be electrically driven at two speeds:

The double lever tensile testing machine for cement briquette is available in different ranges. Loading is applied automatically by lead shots flow in manually operated units and by a travelling weight on the lever in electrically operated model. The loading is controlled at the rate of 226.7kg/minute and measured to 0.05kg. The machines are fitted with precision gunmetal jaws and are provided with levelling feet. It is available in two capacities
